Who cares who copied who? GUI came from Xerox and Apple used their idea and later Microsoft used it as well. In the grand scheme of things, does it matter where something came from? Should Microsoft have continued to use DOS because of not wanting to copy Xerox or Apple? Should Apple have continued their trend of bad OS's like OS9 because they didn't want to copy a Unix based OS's? Doesn't it make more sense to use all of the best technologies possible or should they stop using certain technologies because we worry about not being original. Does it really matter to you that Android had folders and multitasking before ios did? I bet you could care less what they copied as long as they are improving the device. Apple never really comes up with an idea on their own. What they are good at doing is taking a good idea or technology, refining it, then marketing it well like they did with a tablet device.
